Yeah - thanks for catching this.. was planning on fixing this, but anyways..
f56de327b4c4 ARM: dts: dra72-evm: Add extcon nodes for USB

Are the patches that introduce the "ti," binding... Roger: since this is
introduced by your patches... Ccying you as well. weird since checkpatch
does not complain..

While at it, do you want to fix up (+Seb):
a) Documentation/devicetree/bindings/i2c/i2c-pxa-pci-ce4100.txt which
also seems to refer to ti,pcf in example (introduced by df2634f43f51
x86: dtb: Add a device tree for CE4100 )
b) arch/x86/platform/ce4100/falconfalls.dts as well?
